Application filed May 22, 1915. Serial No. 29,933.

To all whom it may concern: a 1

Be it known that I, JAMES ROWE, citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois have invented certain newa'n'd useful Improvements in Book-Pad Adjusters for Au tomatic Book-Trimming Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to automatic book trimming machines of the type particularly illustrated and described in Letters Patent No. 1,003,679 dated Sept. 19, 1911,- and No.

. 1,076,726 dated October 28, 1913, and has for its particular obj ectto provide means for adjusting the pile of books to be trimmed relatively to stop gages therefor for prop'- erly positioning all of the books in the pile relatively to the trimming plane of the trimming knife for the front edge of'said pile of books. V I

In machines of the type referred to the books are primarily fed through the said trimming plane against disappearing gages and upon a carrier for the book pile which is equipped with means for engaging the latter as the gages disappear for carrying said book pile from the first-named trimming plane to the trimming planes of knives for trimming the ends of the books.

As feeding the book piles manually to the first-named trimming plane is very dangerous, the machine is equipped with a suitable book-pile feeding mechanism such as is desired and claimed in my copending application Ser. No. 29,932, or such as is illustrated and described in Letters Patent No. 1,118,152,

granted to me November 24, 1914. In the feed mechanism illustrated and described in said application and last-named Letters Patent respectively, the books are pushed over the surface intersected by the trimming plane of the front trimming knife and against the said disappearingstop-gagesfor properly positioning" the book pile relatively to the trimming plane. In practice it has been found that as the book piles are relatively heavy the frictional resistance to the sliding of the book-pile over said surface causes the lowermost book or books of the pile to lag'in that the lower portion of the s ecification of Leas; mat.

Patented an, 25', 191i".

bottom book pulls the bound edge thereof out of alinement with the higher books of the pile so that the rearor bound edges of said lower book or books are not disposed in contact with the saiddi'sappearing gag s, and, accordingly, pile the said lower book or books not properly positioned as aforesaid will not be trimmed to the desired dimensions. This is due also to the fact that the pusher engaging the book pileto move the same'into position against said disappearing gages must of necessity be sufiiciently yielding to in trimming the said book fingers" prevent injury to the book pile or breakage of the feed mechanism by exerting too strong a pressure against the said disappearing gages.

be trimmed is necessarily rough and uneven owing to the fact that the untrimmed leaves of the book project varying distances from 'the bound edge oredges of said books, and

it is, therefore, impossible to adjust the feed mechanism to feed said book pile with sulficient accuracy to' enab'l e'rigid pusher fingers or devices to be used.

The main object of the present invention,

therefore is to I provide means cooperating with the book 'pile conveying or feeding mechanism in machines in which such mechanism is employed to give to the lower book or books of the book-pile, a final impetus to throw the same against the said disappear ing gages so that all books in the pile will be properly positioned relatively to thetrimming knife for trimming'the front edges of the books.

In the accompanying drawings I have illustrated only so much of a book-trimming machine to which the present invention is applicable as willbe n un'd'erstanding'of the being had to the aforesaid several patents for a complete understandingof the book trimming machine per 86 to which the'present invention constitutesan attachment.

In said drawings illustrating a lsui'table embodiment of the invention: Figure 1 is a view in vertical longitudinal section partly in elevation of the front end portion of a book trimming machine of the type aforesaid equipped with anxattachment constructed in accordance with my invention, Fig. 2 is a vertical transverse section of the same on the line 22 of Fig.

The front edge of the book pile to ecessary to a complete invention; reference Fig. 3 is a fragmentary detail plan section on the line 3-3 of Fig. 1. Fig. 4 is a detail vertical longitudinal section on the line 4-4 of Fig. 2. Fig. 5- is a detail perspective view of one of the ad justing shoes employed. Fig. -6 is a detail view in side elevation of the cam for actuating the adjusting mechanism and so much of the latter as is requisite to comprehension of its operation.

In said drawings 1 indicates the frame in which the trimming knife for trimming the front edges of the book pile is movable, the cutting bed for said trimming knife being disposed between the ends of the book pile supporting surface 2 over which the book pile travels from an initial position to the right of the said trimming frame 1, reference being had to Fig. -1, and the stopgages 3 against which the backs of the books of the pile bear to properly adjust said books to cause the front edges to be trimmed by the said trimming knife. The said gages 3 are vertically movable in guides 4 and are reciprocated at intervals by means of the arm 5 mounted on a rock-shaft 6 which is actuated by means of the cam 7 through the intermediacy ofv the rod 8. The book-pile when disposed against the said gages 3 is partially supported upon the endless carrier 9 trained over the drum 10 rotatably mounted between the cutting bed for the trimming knife and the said gages 3, said drum being rotatably mounted on a relatively large hollow rigid drum 10 suitably supported on the rigid shaft 10. The books are positioned or shoved over the said surface 2 by means of suitable devices described and claimed in said copending application or manually, and the backs thereof are thus brought into contact with the front edges ofthe gages 3 while the edges to be trimmed lie upon the cutting bed of said trimming knife. It will be seen that the book-pile supporting surface of the carrier 9 is disposed between the side portions of the book supporting surface 2 rearwardly of the trimming plane and that said gages 3 are disposed at either side of said carrier 9 and the said drum 10, over which the carrier is trained. Said supporting surfaces 2 are cut away on their opposed side edges at either side of said drum 10 to receive the shoes 11, the upper surfaces of which are normally flush with the upper surfaces of the supporting table 2 and the upper surface of the carrier 9. One of said shoes is disposed at either side of said drum and each thereof is provided in its body portion 12 with two openings 13 in which stud shafts 14 engage. Each of the latter is rotatably engaged with a short crank arm 15 rigid with rock shafts 16 and 17 respectively, journaled in bearings carried by hangers 18 mounted upon the lower face of the book supporting table 2 contiguous to the inner opposed side edges thereof. On said shaft 16 there is rigidly mounted a spur pinion 19 which meshes on said shaft 16; said rack bar being carried by a reciprocable rod 22 provided with a bifurcated lower end engaging the shaft 23 on which the cam 7 is carried and which is provided between its ends with an anti-friction roller 24 engaging in the groove of a cam 25 by means of which said rod 22 is reciprocated at regular intervals in synchronism with the gages, 3, the trimming knife and the feed mechanism and other parts of the machine to cause said shoes 11 to be raised and lowered at proper intervals to effect adjustment of the book pile as previously set forth. In rocking the said shaft 16 the upper or book-engaging surface of the shoes 11 will move upwardly and rearwardly toward the. stop gages 3, as shown in dotted lines in Fig. -4-, thereby causing the bottom book or books of the pile to be adjusted against the gages. The said shoes 11 have, as shown, very small surfaces engaging the books and such surfaces are very smooth. Thus in moving to the position shown in dotted lines said shoes ooact with whatever means are employed for feeding the book pile to position the same against said gages and in performing this function they continue to move in the same direction until their upper surfaces are again in the plane of the book-supporting surfaces of the carrier and the table 2 thereby obviously depositing the book-pile upon the supporting surfaces 2 and carrier 9. They now remain in this position until the front edge of the pile has been trimmed and the same has been removed by the carrier 9. Thereupon they are returned to their first position indicated in full lines in Fig. 4 ready to receive the next book-pile.

The groove of the cam 25 is concentric with the axis of rotation of said cam through an arc of about two hundred eighty degrees and while the roller 24 is engaged in this part of said groove the shoes 11 will remain in the position shown in dotted lines in Fig. -6-. During this period the front edge of the book-pile is trimmed and the carrier 9 then removes the same. Then the roller 24 is thrown into the part of greatest radius of the cam-groove thus returning the shoes to the position shown in full lines in Fig. 4 where they remain during only a very short interval in which the next suc' ceeding book-pile to be trimmed becomes disposed in their path, whereupon the foregoing operation is repeated.

As previously stated the lower book of the pile is distorted rather than moved relatively to the upper books of the pile, as will occur when the covers of a bound book are moved in opposite directions relatively to the bound edge while the book is closed. In

paper bound catalogues, directories, and periodicals this distortion of the bottom book will readily occur in sliding the bookpile over the supporting surface and my de vice is intended and adapted only to restore the book to its normal condition as it a proaches its final position so that all books in the pile may be accurately and uniformly trimmed.

Whilethe invention is ed to be used conjointly feeding means described and claimed in my aforesaid copending application it will be understood, of course, that the same is capable of use independently thereof and may be used in a hand fed machine, equipped with mechanical feeding means other than that particularly shown and described in the aforesaid copending application, and the aforesaid Letters Patent.
